Hi,
I want to clarify my mail from earlier today regarding the recovery of the network / relays.
I wrote that i expect business as usual within 2-3 days for the vast majority of the relays. That does not mean that everything is the way it was before.
When the content of the /keys directory is gone you have basically a new relay and therefore the process of getting flags starts from scratch.
Roger posted an excellent article regarding the life cycle of relays:
